Image error我有2个样式文件。通过单击按钮,我想从AppTheme切换到AppTheme2。怎么做?
请注意,原色带有代码colorPrymary2。那会完全改变我的应用程序的颜色,这就是我想要的。
Manifest.xml
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
styles.xml
<resources>
<style name="AppTheme" parent="Theme.AppCompat">
<item name="android:windowBackground">@drawable/background</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme2" parent="Theme.AppCompat">
<item name="android:windowBackground">@drawable/background</item>
<item name="colorPrimary">@color/colorPrimary2</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
</resources>

只需使用onCreate()方法即可!
getApplication().setTheme(R.style.yourtheme);
